San Diego -- If you had April 18 in the "Bruce Bochy: We've got to get these bats going" pool, congratulations, and don't spend all the winnings in one place.

Bochy has had to utter that phrase far too many times in his Giants tenure. Friday night's 2-1 loss to the Padres provided him a perfect opening to drag it out for the first time in 2014.

Matt Cain got Cained for the second consecutive start, and this might have been more maddening than his 1-0 loss to the Rockies.

Chris Denorfia tripled with one out in the first inning and scored on Hector Sanchez's passed ball. The changeup cut way off the plate. Sanchez tried to backhand the ball and seemed surprised when he looked into an empty glove.

The ball rolled to the backstop, allowing Denorfia to score the only run against Cain in seven innings.

Juan Gutierrez allowed Yasmani Grandal's pinch homer in the eighth, which enabled the Padres to withstand Brandon Belt's homer in the ninth against Huston Street.

The Giants played their eighth consecutive one-run game for the first time since 1910, during the Dead Ball Era, which nobody should confuse with their current Dead Ball Era.

They are 7-for-56 with runners in scoring position over the past seven games and demonstrating that fears about their lack of depth were justified.

Take a pitcher on the upswing (San Diego's Tyson Ross). Have him face a lineup missing two regulars (Buster Posey, Michael Morse) that includes two key hitters in a season-long slump (Pablo Sandoval, Hunter Pence), and the results were predictable.

"They're big boys. They've got to fight through this," Bochy said. "I think without question a couple of guys are pressing. That's what we've got to stop doing, going out of the strike zone. We've been doing that quite a bit."

The game's final pitch was a great example. With Pence on second base, Street threw a high 1-2 fastball, hoping Sanchez would chase. Sanchez obliged, and the Giants were done.

"I tried to do too much in that at-bat," Sanchez said. "It happens. Everybody wants to get a good hit in that situation. You have to be under control. Try to relax. That's best for the team. It's frustrating."

But not as frustrating as his first-inning passed ball. Cain acknowledged the changeup cut quite a bit away from the outside-corner target, but Sanchez took the blame for missing it with his backhanded stab.

Asked if he looked at the pitch on video, Sanchez said, "No. I don't want to get mad. I'll probably break the computer if I watch that."

Bochy insisted before the game that Posey and Morse were not hurt, aside from Morse's mild hamstring tightness, and just needed days off. Both pinch-hit in the eighth, Morse grounding out and Posey striking out.

If they were healthy, it's odd that Bochy would sit both because Cain had lost his previous start 1-0 and the offense had nearly been blanked by the Dodgers on Thursday.

It was same-old, same-old for Cain, who has gotten zero, one or two runs of support in 101 of his 269 major-league starts. Cain has allowed two runs (one earned) in 14 innings with 16 strikeouts over his past two starts. He lost both and is 0-3.
